LUBRICATOR Filed Feb. 26. 1929 Patented Feb. 7, 1933 GEORGE W. QUIVEY, OF TACOMA, WASHINGTON LUBRICATOR Application filed February 26, 1929. Serial No. 342,766.

This invention relates to lubricators and has relation more particularly to a device of this kind especially designed and adapted for use in connection with internal combustion engines and which serves to lubricate the cylinders incident to the pulsations of the engine.

It is an object of the invention to provide a lubricator of this kind which operates to effectively supply the desired lubricant within the cylinders of the engine, resulting in desired lubrication of the valve stems and wherein the lubricant is delivered within the cylinders in a manner to keep down carbon deposits.

It is also an object of the invention to provide a device of this kind including a container adapted for direct communication with the intake of an internal combustion engine, said container being in communication with a source of lubricant supply and wherein means are arranged within said container for maintaining the lubricant therein substantially at all times at a fixed level.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my im proved lubricator whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein c Figure 1 is a vertical sectional view taken through a lubricator constructed in accordance with an embodiment of my invention with certain of the parts in elevation;

, Figure 2 is a sectional view taken substantially on the line 22 of Figure 1;

Figure 3 is a fragmentary sectional view taken substantially on the line '33 of Figure 2..

As disclosed in the accompanying drawing, 0 denotes a container, the walls of which be- 0 ing preferably of glass, having its bottom 1 closed and 2 its opposite or upper end open. This container C is seated upon the base plate 2 of metal or other desired material, while the upper end of the container C is adapted. to be closed by a lid 3, said lid 3 and the up per edges of the container C having interposed therebetween a gasket 4 thus assuring a hermetic seal.

The lid 3, as herein disclosed, is held in applied position through the instrumentality of the U-shaped member M, the intermediate section 5 of which underlying the base plate 2 with the side arms 6 extending upwardly of the container 0 at diametrically opposed points. The arms 6 terminate in inwardly disposed extensions or fingers 7 for'contact from above with the applied lid 3.

The central portion of the section 5 has threaded therethrough a shank 8 having contact from below with the central portion of the base plate 2 whereby the member M opcrates effectively to maintain the plate 2, the container C and the lid 3 in desired assembly. The portion of the section 5 defining the opening 9, through which the shank 8 is threaded, is defined by a depending lug or boss 10 with which is adapted to have direct contact a locking or holding nut 11 threaded upon the shank 8. The outer end portion of the shank 8 is provided with a conventional head 12 to facilitate the desired manipulation thereof.

The interior of the container C provides a float chamber F in which the lubricant'L is adapted to be maintained at substantially a constant level. This lubricant L constitutes preferably an oil of a character especially advantageous for cylinder lubrication.

The central portion of the lid 3 is provided with a block 14 extending radially thereacross and which also depends from the base or bottom plate 15 of a reservoir R. This reservoir R is of desired capacity'and in the complete assembly the reservoir R is in communication with the float chamber F through the medium of a port 16' disposed 95 through the block 1% andthe lid 3 and also the bottom plate 15 of the reservoir R. The reservoir R has its upper end open and said open end'is closed by a cap 17 herein disclosed as of a type adapted to be threaded upon the 100 reservoir R and the central portion of said cap is provided with an air vent 18. The bore or port 16 intermediate its ends is restricted, as at 19, and coacting with said restricted portion is a needle valve 20. This needle valve 20 is of a length to extend a material distance downwardly within the float chamber]? and is freely disposed through the central portion of a float member 21. The needle valve 20 within the float chamber 'F and at a point above the float member21carries a disc 22. This disc 22 is provided in its periphery at diametrically opposed points with the notches or recesses 23 which receive the posts 24 depending within the chamber F from the applied lid 3. 1 By this arrangement the disc 22 is held against rotary movement yet offers no hinderance .or obstruction to the desired endwise movement of the needle valve 20.

V The lower or free end portions ofthe posts v2 L are pivotally connected, as at 25, withthe reduced extensions 26a of the rock levers 26. These levers, as particularly illustrated in Figure 3, are arranged side by side and their outer or free end portions are in contact with the upper face of the float member 21. The reduced portions 26a project beyond the posts 24 a desired distance and carry the weights '27 whereby the desired swinging movement of the levers 26 is facilitated incident to the rise and fall of the float member 21.

The levers 26 are provided with upstanding fingers 28 for contact from below with the disc 22, the actionbeing such that upon rise of the float member 21 the needle valve 20 will be moved into closed position and thereby shut ofi' the flow of the lubricant from the reservoir B into the float chamber F. As the with a pocket or recess 29 having in com-' munication with the inner end portion thereof a port 30. This port 30 is continued by an elongated tube 31 which, in the assembled device terminates at a point in close proximity to the bottom 1 of the container C. Threaded within the pocket or recess 29 is a headed shank 32 having disposed axially therethrough a port 33; This port 83 istin communication with the atmosphere and provides means whereby requisite suction may be haddown through the tube 31 and up through the lubricant within the chamber F to the engine cylinders as a result of the suction created by the engine pulsations. The air drawn through the tube 31' may be regulated or controlled uponproper adjustment of the shank 32.

The end portion of the block 14 remote from the pocket or recess 29 is provided with a port 34 disposed lengthwise of the block 1i and which has its inner end portion continued by a port 35 in communication with the chamber F through the open top of the container C. Leading from the port 34 is a conduit36 which is adapted tojhave suitable communication with the intake mani fold of an internal combustion engine where- 'bythe lubricant is properly conveyed within the cylinders;

It is to be particularly noted that the lubricant within the container C is at all times maintained at a constant level. This is of advantage as it assures aldelivery of a thick quantity of lubricant within the cylinders of V From the foregoing description. it is f thought to be obvious that a lubricator constructed in accordance with myinvention is particularly well adapted for use by reason of the convenience and'facility with .whichit may be assembled and operated, and it will s also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish .to be understood as limiting myself to'theprecise arrangement and formation of the several parts herein shown in carrying out my invention in practice exceptas hereinafter claimed. a
